1. Plural of hydroxyprol­ine; amino acids formed by the hydroxylation of proline, found especially in collagen and other structural proteins.
Usage: technical; biochemistry

Examples

• Hydroxyprolines are abundant in collagen, making up about 10% of its amino acid composition.
• The presence of hydroxyprolines in bone tissue contributes to its structural integrity.
• Vitamin C is essential for the hydroxylation of proline to form hydroxyprolines.
• Hydroxyprolines stabilize the triple helix structure of collagen molecules.
• Researchers measured hydroxyproline levels to assess collagen turnover in the patient's tissues.
